醋酸纤维素的降解性研究进展

介绍了醋酸纤维素的生物降解、水解、光解的降解机理与研究现状，并对影响醋酸纤维素降解速率的因素进行了探究。从现有研究中可知，影响醋酸纤维素降解速率的主要因素为醋酸纤维素自身的分子结构（如取代度、取代度分布及结晶性等），物理改性、化学改性及增塑改性会通过改变醋酸纤维素的分子结构，进而影响醋酸纤维素的降解性能。最后，总结了醋酸纤维的应用领域，并做出了展望。

Research progress in degradability of cellulose acetate

This paper introduced the degradation mechanism and research status of cellulose acetate biodegradation， hydrolysis， and photolysis. The factors that affect the degradation rate of cellulose acetate were explored. Based on the current studies， the molecular structure of cellulose acetate was the main factor that affects the degradation rate of cellulose acetate. The physical modification， chemical modification， and plasticizing modification affected the degradation performance of cellulose acetate through changing the molecular structure of cellulose acetate. Finally， the application fields of acetate fiber were summarized and its prospect was analyzed.
